INCREASING THE ACCURACY OF REENTRY VEHICLES AND PROVIDING THE CAPABILITY TO ATTACK IMPRECISELY LOCATED OR RELOCATABLE TARGETS ARE GOALS WHOSE REALIZATION WOULD SUBSTANTIALLY ENHANCE THE SECURITY OF THE UNITED STATES AND REDUCE THE CHANCE OF NUCLEAR WAR. MOST SIGNIFICANT IS THE POTENTIAL FOR INCREASING THE ACCURACY TO THE POINT WHERE NON-NUCLEAR WEAPONS COULD BE EMPLOYED AGAINST STRATEGIC TARGETS. THESE GOALS SHOULD BE ACHIEVABLE THROUGH APPLICATION OF EXISTING OR NEAR-TERM TARGET DESIGNATION AND GUIDANCE TECHNOLOGIES. BD SYSTEMS IS PROPOSING A NEW AND INNOVATIVE TARGET DESIGNATION CONCEPT USING BISTATIC SYNTHETIC APERTURE RADAR TECHNIQUES. THIS NEW CONCEPT HAS THE ADVANTAGES OF BEING OPERABLE IN ALL WEATHER CONDITIONS AND BEING POTENTIALLY IMPLEMENTABLE WITH ONLY MODERATELY SIZED SENSORS AND RECEIVERS ON THE RVS AND ON THE DESIGNATION PLATFORMS. THE OBJECTIVES OF THIS PHASE I STUDY ARE TO ASSESS THE FEASIBILITY OF THIS NEW CONCEPT, TO ASSESS THE FEASIBILITY OF SEVERAL OTHER TARGET DESIGNATION SCHEMES, TO DETERMINE THE TECHNOLOGIES REQUIRED FOR THEIR IMPLEMENTATION, AND TO IDENTIFY THE MOST PROMISING SCHEMES FOR DETAILED ASSESSMENT IN PHASE II.
